DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/0/CPU0:router# configure
Enters global configuration mode.
Step 2
multicast-routing [address-family {ipv4 | ipv6}]
Example:
RP/0/0/CPU0:router(config)# multicast-routing
Enters multicast routing configuration mode.
• The following multicast processes are started:
MRIB, MFWD, PIM, IGMP, and MLD.
• For IPv4, IGMP version 3 is enabled by default; for
IPv6, MLD version 1 is enabled by default.
Step 3
interface all enable
Example:
RP/0/0/CPU0:router(config-mcast-ipv4)# interface
all enable
Enables multicast routing and forwarding on all new
and existing interfaces.
Step 4
exit
Example:
RP/0/0/CPU0:router(config-mcast-ipv4)# exit
Exits multicast routing configuration mode, and returns
the router to the source configuration mode.
Step 5
router {igmp | mld}
Example:
RP/0/0/CPU0:router(config)# router igmp
(Optional) Enters router IGMP or MLD configuration
mode.
Step 6
version {1 | 2 | 3}
Example:
RP/0/0/CPU0:router(config-igmp)# version 3
(Optional) Selects the IGMP or MLD version that the
router interface uses.
• The default for IGMP is version 3; the default for
MLD is version 1.
• Host receivers must support IGMPv3 for PIM-SSM
operation.
• If this command is configured in router IGMP or
router MLD configuration mode, parameters are
inherited by all new and existing interfaces. You
can override these parameters on individual
interfaces from interface configuration mode.
